Q. Write an expression that is equivalent to 3k−18.3k−18=□(k−?)
Factor Out Common Factor: Factor out the common factor from the expression 3k−18. To factor out the common factor, we look for a number that divides both terms in the expression. The number 3 is a common factor of both 3k and −18. So, we can write 3k−18 as 3(k−6).
Verify Factored Expression: Verify that the factored expression is equivalent to the original expression.To verify, we can distribute the 3 back into the parentheses to see if we get the original expression:3(k−6)=3⋅k−3⋅6=3k−18.Since this is the original expression, our factoring is correct.
